Quick Summary
The PowerLayer men’s compression base layer top is a navy size S thermal shirt for running and training. It is presented as a compression base layer with a light, tight fit and 4-way stretch fabric.
It is also described as a thermal shirt for outdoor sports, so the key buying checks are size, fit and whether you want a close-fitting base layer rather than a looser top.
